Animal ownership has reported financial and nutritional benefits but has also been associated with enteric and respiratory infections, and inadequate sanitation and hygiene can lead to children touching and ingesting animal fecal matter. We identified key indicators for poultry feces management and investigated their social determinants using data from a baseline survey of a randomized-controlled trial of a poultry management training program in rural Western Uganda. The baseline survey was conducted in the Masindi and Kiryandongo districts of Uganda in September 2019, and data collected from 609 households were used. We evaluated indicators for poultry feces management behaviors using scale development methods, including descriptive statistics, bivariate correlation analyses, and Factor Analysis of Mixed Data. We also investigated social determinants of key poultry feces management behaviors using logistic and multinomial logistic regression models. A significant increase in odds of having free-roaming poultry was found for each additional poultry owned (OR = 1.18, P < 0.001). The odds of a household having an observed enclosure for poultry increased by 5% with each incremental poultry owned (OR = 1.05, P < 0.001), and by 4% with increasing wealth with each additional point on the poverty probability index score (OR = 1.04, P < 0.001). Our results also suggest enclosures are intermittently used and constructing them without further intervention likely will not be sufficient for effectively managing animal fecal contamination. We recommend that future studies on animal feces management measure indicators for corralling and feces disposal practices and evaluate their relationship to enteric pathogen exposure and health outcomes. Insights from this work can inform the development of robust indicators of poultry feces management behaviors that can be used for monitoring and evaluation purposes.
动物拥有权据称具有经济和营养方面的益处,但也与肠道和呼吸道感染有关,而且卫生条件和习惯不佳可导致儿童触摸和摄入动物粪便。我们确定了家禽粪便管理的关键指标,并利用乌干达西部农村地区一项家禽管理培训方案的随机对照试验的基线调查数据,调查了这些指标的社会决定因素。基线调查于 2019 年 9 月在乌干达的马辛迪区和基永多戈区进行,使用了 609 户家庭的数据。我们采用量表制定方法评估家禽粪便管理行为的指标,包括描述性统计、双变量相关分析和混合数据因子分析。我们还利用逻辑回归和多项逻辑回归模型,调查了关键家禽粪便管理行为的社会决定因素。研究发现,每多养一只家禽,自由放养家禽的可能性就会显著增加(OR = 1.18,P < 0.001)。每多养一只家禽,家庭拥有观察到的家禽围栏的可能性就会增加 5%(OR = 1.05,P < 0.001),而随着贫困概率指数得分每增加一个点,这种可能性就会增加 4%(OR = 1.04,P < 0.001)。研究结果还表明,围栏是间歇性使用的,仅建造围栏而不进一步干预可能不足以有效管理动物粪便污染。我们建议,未来关于动物粪便管理的研究应衡量圈养和粪便处理做法的指标,并评估这些指标与肠道病原体暴露和健康结果的关系。这项工作的见解可以为监测和评估目的提供家禽粪便管理行为的稳健指标。
